粉红粘帚菌

  科学家日前在南美洲发现一种罕见菌类,可以将植物肥料分解合成一种碳氢化合物,其功效和柴油非常相似。专家表示,这种菌类将有望在解决世界能源短缺和减少环境污染的问题中发挥重大作用。

  这种真菌名叫粉红粘帚菌,生长在巴塔哥尼亚的热带雨林中,它能够将植物纤维素直接转变成生物燃料——自然地分解产生碳氢化合物,其成分和应用于车辆中的柴油等燃料非常相似。专家认为,这种真菌将是一种潜在的绿色的能源。

     负责该项研究的美国蒙大拿州大学教授格里,经常在阿根廷和智利边境的巴塔哥尼亚热带雨林中研究新奇的菌类。格里教授表示:“我们对这种真菌分解出的化合物进行了测试,发现全是碳氢化合物及其衍生物,这个结果是此前没有预料到的。如果这种菌类被用来生产燃料,将能省去现在生产制作燃料过程中的一些环节。当然,现阶段还需要通过进一步的实验证实可行性。”

  格里教授表示,这种真菌有双倍的价值,因为它含有独特的基因,能生产出将纤维素分解成柴油气体的酶。从理论上说,当把它嫁接到其它生物体中时,这些真菌将更加活跃,能更加有效地生产柴油。

  此外,这个发现还有助于人们了解石油的形成过程。此前普遍被接受的有关石油形成的理论是——动植物在热和压力的作用下经过上百万年形成了石油。

  有关这项研究的报告已经发表在11月出版的《微生物》杂志上。
